A thing I’ll never understand is why a small startup would use a recruiter to try and hire a specific person, instead of having one of the founders/employees do it

One last physics assignment, this time by my student Ty Trusty, implementing vertex-block descent: github.com/tytrusty/pba...
Get's about 5 chickens per second on my workstation GPU.

There's a new and very neat-looking SIGGRAPH Asia paper on constructing the swept volume based on the path of a moving (possibly deforming) object. Check it out!

for anyone who hasn’t seen this yet: the SAFE Act would prohibit any faculty who have *ever* worked with Chinese international graduate students (including retroactively, in the past five years) from receiving federal funding in the future: www.science.org/content/arti...

absolutely insane the things people are using Python for when there is C#, a language that is better in every conceivable way
I'm such a C# shill but,
any time I hear someone say "the garbage collector slows things down too much" I feel like they're not aware of just how many tools you have to avoid heap allocations
it seems to me whatever work that entails, it's almost always less work than using an unmanaged language

This is a very good clip of Guillermo del Toro on the value of art. The value of human-made art is, in part, based on what the artist experienced that made them want to make the art. That is what we pay for. That is what AI does not have.

learned today that boost.polygon has no dependencies on the rest of boost, and it can do a 2D Voronoi diagram for line segments, which means it can be used to find the max-inscribed circle of a polygon (which is much harder than min-containing circle!). And it's quite fast, too.
